Not understanding the lyrics can be part of the appeal, because it makes them less distracting.

Understanding a little can make embarrassingly cheesy and saccharine pop lyrics take on a profound poetic quality.

Growing up on anime and Japanese video games is probably a big contributor to finding the melodies appealing.

Also, dude's got a giant concert video in view pretty much constantly, so image is probably part of it.

hope this helps
